SPECIFICATION forming part of Letters Patent No. 750,442, dated January26, 1904.

Application filed November 6, 1903. Serial No. 180,088. (No model.)

T0 a/ZZ whom, it mfc/Jy concern/.-

Be it known that 1, DANIEL S. EVERETT, of Macedon, in the county ofWayne and State of New York, have invented a new and useful Improvementin Dumping-Wagons, which improvement is fully set forth in the follow`ing specica'tion and shown in the accompanying drawings.

My invention is a dumping-wagon intended for use in hauling and quicklyand 'conven iently discharging loads of the coarser merchandise orsimilar materials, as coal, earth, and the like, and for handling farmproducts and also for use in doing heavy truckwork, as hauling andreadily unloading safes, heavy machinery, steam-boilers, &c. The sidesand the bottom of the wagon box or body, which is commonly made of metalsheets, are rigid and without movable joints, and for the purpose ofdischarging or dumping the load the box is moved longitudinally bodilybackward over the rear axle and then tilted, discharging the contents inbulk on the ground or sidewalk in rear of the wagon. Provision is alsomade in this structure for controlling the box by .positive means oraction at every point while being tilted to the end that when partly`elevated it shall.r not by accident move back again toward itshorizontal position.

The invention is hereinafter fully described, and more particularlypointed out in the appended claims, reference being had in thisspeciiication to the accompanying drawings, forming a part thereof.

Figure 1 is a plan of my improved dumping-wagon as ready for use. Fig. 2is a side elevation of the wagon with the box shown by dotted lines ashaving been moved longitudinally backward. Fig, 3 is an elevation of therear end piece seen as indicated by arrow 3 in Fig. 6showing it in vitstilted or open position. Fig. 4 is a v ertical transverse section of thewagon-box,taken as on the dotted line 4 4 in Fig. 1, showing an insideelevation of the end piece.f Fig. 4t is an inside eleva-4 tion of theright-hand stake, showing the vertical `roller,` the section being as onthe dotted line 4% in Fig. 16. Fig. 5 is a rear end view of the wagon.Fig. 6 is a side elevation'of the rear parts of the wagon, showing thebox in its rearward and tilted position. Fig. 7 is a verticallongitudinal section of parts at the rear end of the wagon, taken on thedotted line 7 7 in Fig. 1, further showing the construction. Fig. 8 isan elevation of the inner face of the right bent channeled guide for theforward end of the box detached. Fig. 9 is a vertical transverse sectionof the ratchet and the shaft on the dotted line 9 in Fig. 14. Fig. 10 isan elevation of the ratchet and associated parts at the left end of theoperating-shaft seen as indicated by arrow 10 in Fig. 14, the shaftbeing transversely sectioned on the dot-V ted line at the point of thearrow. Fig. 11 is a front elevation of the Wagon with parts omitted,`thetongue being transversely sectioned on the dotted line 11 in Fig. 1.Fig. 12 is a vertical transverse section of a part of the wagonbox onthe dotted line 12 12 in Fig. 14, parts being broken away, the guidesand a forward roller in part being vertically sectioned along the axisof the sill. Fig. 13 is a side elevation of parts at the forward end ofthe wagonbox seen in the direction indicated by arrow in Fig. 12, partsbeing omitted. Fig. 14 is a plan of the frame of the wagon with someassociated parts, the bent guides being obliquely sectioned on thedotted line 14 in Fig. Gand a part at the forward end of the frame beingbroken away and horizontally sectioned across the axis of the associatedroller. Fig. 15 is a cross-section of the wagon-box and the frame on thedotted line 15 15 in Fig. 1, further showing the rear parts ofthe wagon.Fig. 16 is a rear elevation of the bolster and associated parts, partsbeing broken `out and other parts vertically sectioned along the axis ofthe rear roller. Figs. 4t, 7 to 10, 12, 13, 14, and 16 are drawn tovarious scales larger than that of the remaining gures.

Referring to the parts shown, A is the front axle of the wagon, B the`rear axle, and C the box or body mounted over the axles.

D is a horizontal frame, preferably of angleiron, supported by the axlesbelow the box C, the rear end of the frame being secured rigidly to thebolster E of the rear axle, which bolster constitutes, practically, anintegral part of the frame. The bolster is formed with vertical stakes cc at the sides of the box, be-

IOO

tween which stakes the box may freely move longitudinally and tilt inthe act of dumping or discharging the load.. A roller Figs. 2, 4%, 5, 6,7, 14, 15, and 16, held horizontally over the bolster with bearings inthe stakes c, is provided for the box C to rest upon, so that said boxmay be moved easily backward and forward over the frame. For the heavierwork I also provide the stakes a a with vertical. rollers c, Figs. 4 and16, to enable the box to be easily moved, these side rollers beingparticularly useful. at times when the wagon Y is to be unloaded whilestanding upon uneven ground with the box leaning to one side.

The forward end of the frame D is provided with upwardly bent hollowbars or guides G G, Figs. 1, 2, 5, 6, 8, 11, 12, and 14, one at eitherside of the box C and parallel therewith and between which the boxfreely moves. rIhe upper ends of the guides ordinarily extend above thesides of the box, and these guides, which are preferably made ofchannel-iron, have their open sides turned inward, as shown in theiigures. The forward end of the box C is held upon a cross bar or sillF, provided at its overhanging ends with rollers c c, occupying thechannels cl CZ of the guides, which channels the rollers traverse whenthe box is moved horizontally or tilted. r1`he ends of the sill F and ofthe rollers c c nearly touch the bottoms of the channels d Z of therigid guides G Gr, on account of which the latter serve to confine theforward end of the box and prevent sidewise motions of the box. Also therollers c c being always in the channels of the guides serve at alltimes to control the positions of the box, whether horizontal orinclined, by positive action.

The guides G G are each provided with a set or series of equal sprocketse fg, (one overhanging each end and one near the middle,) carryingchains71, /t at the sides of the box, the several sprockets being held byshort arms c', secured to the guides. A shaft z, Figs. 1, 2, 5, 6, 9,10, and 14, is provided, crossing the frame D and resting in bearings ZZ, secured to the frame, said shaft having overhanging driving-sprocketsm m for the respective chains L. This shaft is also furnished with ahand-crank 11 by means of which to revolve the shaft and drive thechains, the

sprockets m m being, respectively, in the vertical planes of the saidtwo sets of sprockets on the guides G Gr. These chains are connectedwith the wagon-box by rigid studs 0 0, Figs. 1, 2, and 6, projectinghorizontally from the opposite sides of the box near the forward end, onaccount of which when the crank is turned one way or the other'the boxwill be caused to move correspondingly. Now it will be understood thatif the crank'be turned in the direction indicated in Fig. 2 the box Cwill be carried horizontally backward until the traverse-rollers c creach the bends p p in the guides G G, when as the rollers move upwardlyalong the inclined parts of the guides the box will be tilted andfinally brought to the position for dumping the load (shown in Fig. 6)when the rollers reach the highest points in the guides. A reversemotion of the crank will primarily bring the box to its horizontalposition and then forward to its full normal position, (shown by fulllines in Figs. 1 and 2,) the rollers c o encountering stops t, Figs. 8and 14, when the box is fully forward, and it will be observed that allthese various motions of the box will be made on roller-bearings, thebox resting constantly on the main roller I) at the rear end and held atthe forward end on the minor rollers c c. In placing the middlesprockets ff care is taken to so relatively locate them with referenceto the bends p p in the guides G G that the studs 0 0 will easily passthe sprockets, while the rollers 0 c, unyeldingly controlled by theguides, move freely along the latter and around the bends. The shaft 7cis also provided with a ratchet 1, Figs. 9, 10, and 14, near the crankn, a pawl s, pivoted at the side of the frame D, engaging the teeth ofthe ratchet, as shown. By means of this ratchet and the pawl thewagon-box will be caught at any point in its tilted positions and soheld and prevented from returning undesignedly to a horizontal positionshould the crank be at any time temporarily unmanned. When the box hasbeen moved back and tilted to discharge its load, as stated, and it iswished to return it to place, the pawl s is iirst temporarily turnedback oif of the ratchet.

The box C is open the at rear end, and when handling coal or sucharticles that will roll or flow I employ with it a tilting orvertically-turning rear end piece H, Figs. 1, 3, 4, 5, 6, 7, and 15,which acts in the two capacities of end-board for closing the box and adelivery-spout. This end piece is held to the rear end of the box insome suitable hingejoint fr of common kind and so as to tip backward toopen the end of the box when in the act and for the purpose ofdischarging the load. rlhe end piece comprises three verticalrectangular sides or walls u u and c, joined at right angles, each inequal depth with the box, the side c being transverse of the box andconstituting the end-board proper for the box, the sides u u beingparallel with and normally just within the respective sides of the box,as shown.

w w are angular blocks or bodies in part filling the corners between therespective sides u u and the end wall c, giving to the end piece whentilted or thrown back, as shown in Figs. 3 and 6, the form or characterof a contracted delivering-spout for the box. When tilting, theend pieceH is designed to turn backward through ninety degrees of arc, as shownin Figs. 3 and 6, which brings the side o in the plane of the bottomboard of the box. In this position the end piece constitutes an IOO IIO

open rearwardextension or discharging-spout for the box, the part oforming a temporary extension of the bottom board and the sides u u atthe same time constituting rearward extensions of the sides of the box.To arrest the backward motion of the end piece and hold it in positionwhile the load is being discharged through it, any simple means may beemployed, as an ordinary stop-chain or a rigid tongue m, Figs. l, 2, 4,5, and 6, secured to the under surface of the bottom board and extendbackward, as shown, and provision is also made for operating the endpiece H automatically from the shaft if; by means of a pair of cords orcables 1/ yone at either side of the box. 'Ihe shaft is provided at itsends and outside of the sprockets m m with reels .e z, upon which theforward ends of the cords are wound, the cords passing thence backwardover high carrying-rollers a' a', held at the sides of the box, withtheir rear ends attached to pins secured to the upper part of the sideor part o of the end piece H. As the shaft vis turned to carry back andtilt the box, as stated, the cords will be unreeled from the reels e; zand allow the end piece to tip backward, as shown. A turning of thecrank forward to return the box to its normal place will rewind thecords4 onto the reels, and so bring the end piece to its uprightposition and close the rear end of thebox.

For handling safes or other large and heavy articles, as machinery andthe like, the endpiece H is replaced by a simple hinged endboard ofcommon kind, the reels and the cords being omitted.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. A dumping-Wagon comprising a box, a frame beneath the box, and a maincarryingroller for the box near the rear axle, there being guides on theframe at the sides of the box, and parts carried by the box to traversethe guides, and means for moving the box longitudinally, the guidesbeing bent 'to carry the box out of a horizontal position.

2. A dumping-wagon comprising a box, a frame beneath the box, and a maincarryingroller for the box near the rear axle, and guides on the frameat the sides of the box, and parts carried by the box to traverse theguides, a

shaft with crank on the frame provided with sprockets, a series ofsprockets on each guide coacting with the respective sprockets on theshaft, and chains on the two series or sets of sprockets, connected withthe box.

3. A dumping-wagon having a box, and a frame beneath the box forsupporting it, a rear end piece for the box adapted to turn on bearingson the box to form an open rearward extension for the box, and means formoving the b ox backward on its bearings on the frame.

4. A dumping-wagon having a box, and a frame beneath the box forsupporting the latter, a rear end piece for the box adapted to turn onbearings on the box to form an open rearward extension for the box, saidend piece having inclined parts for reducing the opening at the rear endof the box, and means for moving the box on the frame.

5. A dumping-wagon having a box open at its rear end, an end piece forthe box, consisting of three vertical plates or sides joined, theintermediate side being transverse of the box and serving to close therear open end of the box, and the extreme sides being parallel with andadjacent to the sides of the box, the end piece being held to the box bya hinge-joint and adapted to turn thereon to bring its said intermediateside into the plane of the bottom of the box.

6. A dumping-wagon having a box open at its rear end, and an end piecejoined to the box by a hinge-joint to close said open end of the box,and means for tilting the box and for automatically returning the hingedend piece to its normal or closed position after discharging the load.
